+ * NAME
+ * getdents01.c
+ *
+ * DESCRIPTION
+ * getdents01 - get a directory entry
+ *
+ * ALGORITHM
+ * loop if that option was specified
+ * issue the system call
+ * check the errno value
+ * if failure, log the errno and issue a FAIL message
+ * otherwise,
+ * if doing functionality testing,
+ * if the directory name of the first entry is "."
+ * issue a PASS message
+ * otherwise,
+ * issue a FAIL message
+ * break any remaining tests
+ * call cleanup
+ *
+ * USAGE: <for command-line>
+ * getdents01 [-c n] [-f] [-i n] [-I x] [-p x] [-t]
+ * where, -c n : Run n copies concurrently.
+ * -f : Turn off functionality Testing.
+ * -i n : Execute test n times.
+ * -I x : Execute test for x seconds.
+ * -P x : Pause for x seconds between iterations.
+ * -t : Turn on syscall timing.
+ *
+ * HISTORY
+ * 03/2001 - Written by Wayne Boyer
+ *
+ * RESTRICTIONS
+ * Any restrictions
